Can Prometheus store data into InfluxDB?
In InfluxDB 1. x, the Prometheus metric names become the InfluxDB measurement. Then the Prometheus sample value becomes an InfluxDB field using the value field key (always a float). Prometheus labels will then become InfluxDB tags.
Where are Prometheus metrics stored?
As you can check the Prometheus Dockerfile on Github (https://github.com/prometheus/prometheus/blob/master/Dockerfile#L24), the working directory is /prometheus and that where you will find all the metrics and data. And this is the *Time Series Database * which you can’t decode .
What is difference between InfluxDB and Prometheus?
Prometheus is a database optimized for time series data and an ideal way to store monitoring metrics. InfluxDB is a time series database designed for fast, high-availability storage and retrieval of time series data. It can work as a stand-alone solution, or it can be used to process data from Graphite.
Does Grafana store data?
Grafana works with data, which must be stored in a database before it can be accessed by Grafana. There are several different kinds of databases. Additionally, some other systems can be used to store data, even though their main purpose is not focused on data storage.
How is Prometheus data stored?
Prometheus has a sophisticated local storage subsystem. For indexes, it uses LevelDB. For the bulk sample data, it has its own custom storage layer, which organizes sample data in chunks of constant size (1024 bytes payload). These chunks are then stored on disk in one file per time series.
Is zabbix push or pull?
Zabbix by default uses “pull” model when a server connects to agents on each monitoring machine, agents periodically gather the info and send it to a server. Alternative is “active checks” mode when agents establish connection with a server and send data to it when it need.
Why does Prometheus use InfluxDB as external storage?
For us to store persistent data for longer periods the ‘external storage’ mechanism was used. In this mode Prometheus duplicating its own data to external storage, only external writes are available. Several options were possible but we chose InfluxDB high-available solution. InfluxDB is a reliable and robust storage with many features.
Which is a limitation of local storage in Prometheus?
Note that a limitation of local storage is that it is not clustered or replicated. Thus, it is not arbitrarily scalable or durable in the face of drive or node outages and should be managed like any other single node database. The use of RAID is suggested for storage availability, and snapshots are recommended for backups.
How many hours of data are in a Prometheus block?
Backfilling will create new TSDB blocks, each containing two hours of metrics data. This limits the memory requirements of block creation. Compacting the two hour blocks into larger blocks is later done by the Prometheus server itself.
How often does Prometheus upload data to sidecar?
Thanos SideCar: SideCar runs with every Prometheus instance. The sidecar uploads Prometheus data every two hours to storage (an S3 bucket in our case). It also serves real-time metrics that are not uploaded in bucket. Thanos Store: Store serves metrics from Amazon S3 storage.
